BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum x morifolium, typically grown as a cut flower Chrysanthemum and hereinafter referred to by the name ‘DLFAVAT3’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program is to create new cut flower Chrysanthemum plants with unique and attractive inflorescences.

The new Chrysanthemum plant originated from a cross-pollination in February, 2018 of a proprietary selection of Chrysanthemum x morifolium identified as code number KR 11472, not patented, as the female, or seed, parent with a proprietary selection of Chrysanthemum x morifolium identified as code number KR 2013.1399-1, not patented, as the male, or pollen, parent. The new Chrysanthemum plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in November, 2018.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since November, 2018 has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘DLFAVAT3’. These characteristics in combination distinguish ‘DLFAVAT3’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright plant habit; uniform growth habit.     -   2. Vigorous growth habit and rapid growth rate.     -   3. Durable and robust dark green-colored leaves.     -   4. Strong upright flowering stems.     -   5. Pompon-type inflorescences with pink-colored ray florets.     -   6. Relatively tolerant to high production temperatures.     -   7. Good postproduction longevity.

Plants of the new Chrysanthemum differ primarily from plants of the female parent selection in the following characteristics:

-   -   1 Ray florets of plants of the new Chrysanthemum are less         concave than ray florets of plants of the female parent         selection.     -   2. Ray florets of plants of the new Chrysanthemum are lighter         pink in color than ray florets of plants of the female parent         selection.

Plants of the new Chrysanthemum differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Chrysanthemum have larger inflorescences         than plants of the male parent selection.     -   2. Ray florets of plants of the new Chrysanthemum are pink in         color whereas ray florets of plants of the male parent selection         are reddish purple in color.

Plants of the new Chrysanthemum can be compared to plants of Chrysanthemum X morifolium ‘Delibonbon’, not patented. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Delibonbon’ in ray floret color as plants of the new Chrysanthemum have pink-colored ray florets whereas plants of ‘Delibonbon’ have light purple-colored ray florets.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet (FIG. 1 ) is a side perspective view of a typical flowering stem of ‘DLFAVAT3’ grown as a disbud-type cut flower.

The photograph on the second sheet (FIG. 2 ) is a close-up view of upper (left) and lower (right) surfaces of typical inflorescences and typical leaves of ‘DLFAVAT3’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants grown during the early spring in ground beds in a glass-covered greenhouse in Maasdijk, The Netherlands and under cultural practices typical of commercial cut Chrysanthemum production. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures ranged from 18° C. to 25° C., night temperatures ranged from 20° C. to 22° C. and light levels averaged 7 klux. Plants were grown as single-stem disbud-type plants and were ten weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
